50 (LZZ whom it may concern.-

Be it known that I, Isaac \V. Hnvsnvcnn, ofPhiladelphia, in the countyof Philadelphia and State of Pennsylvania, have invented a certain newand useful Improvement in Machines for Inserting Metallic Staples inPapers, &c., of which the following is a full, clear, and exactdescription, reference being had to the drawings accompanying and forming a part of this specification, in which- Figure l is a horizontalsectional view through the staple-driver and its coacting parts. Fig. 2is a front view taken along the dotted line 1 y of Fig. 1. Fig. 3isaside view from the side occupied by the staple-feeding bar. Fig. 3"shows different equivalent forms of the follower which moves the staplesalong the bar. Fig. 4 is a vertical sectional view along the dotted linegt a of Fig. 1. Fig. is a side view of the machine, from the sideopposite that shown in Fig. 3, and shows the arm raised. Fig. 6 showsthe staple-bar, which I furnish withthe machine, supplied with staplesand ready for use. Fig. 7 and Fig. 7show different but practicallyequivalent forms of the clamp used to hold the staple-feeding bar inplace; and Fig. Sis an enlarged view of the end of the staple-bar andthe parts of the machine to which it is related in place,

The lettering in all the figures is uniform. My invention consists,iirst, in the construction of a selffeeding staple-driviugmachine eitherfor hand or foot or power use, in which the staples are delivered intothe machine, from a longitudinal staple-feedingbar carrying a series ofstaples, which are delivcred into the'machine not directly under theplunger or driver thereof, but alongside the vertical axis of the same,and thence carried laterally under the plunger by atransverselyreciprocating head block or carrier, actuated eitherindependently of or in connection with the motion of the plunger ordriver, so that the staples will not jam against each other in thestaple-guiding channel of the driver from any accidental or incompletemovement of the plunger, asis the case when the staples are fed from afeed-bar immediately under the plunger; secondly, in combining with astaple inserting and clinching machine having a vibrating arm carryingstaplerdriving meohan- (No model.)

so that the latter may he raised to have stapies inserted at the openend of the stapleguiding channel thereof of various sizes, a-

.self feeding device consisting of a staple-carrying bar supplied with aseries of staples pressed forward into the machine external to the lineupon which the plunger operates, and

having a transversely reciprocating head block or carrier constructed tocarry the staples singly across the face of the machine and under theplunger, and adapted to be used eitheras aself-feeding orasingle-feedmachine, may be desired; thirdly, in the use, in a selffeedingstaple-drivingmachine, of a longitudinal staple-carrying bar consistingof a body upon which the corners of the staples rest, lying against eachother, and having their legs extending down along the sides thereof, andprovided with a tongue or flap extending along the length of said bar,attached at one end and having the other free, so that the staples maybe fed directly into the machine by a :follower traveling along the saidbar behind the staples, the flap or tongue acting as a guide for thestaples while being fed into the ma chine singly, and as a protection tothe staples strung upon the bar during transportation thereof, or whennot required for use.

I do not, however, claim in this application the detachable or detachedstaple-holding bar or stick of wood or metal described and shown herein,except as a part of the staple-driving combination in which it is used,as the said staple-holdin g stick forms the subject of a separateapplication dated April 17,1886, Serial No. 199,176, which is nowpending in the United States Patent Office, and in which it is fully ICOing arni,A, which carries at its free end the staple-driving mechanism,and rests by its own weight u pen the paper or other material to bestapled. The base B is provided at its forward end (see Figs. 3 and 5)with a raised clinching-anvil, B, which contains aclinchinggroove, B",upon its upper surface, which may be of any of the forms in use for likepurposes. I show the front of this anvil sloped off, so that papers maybe pushed under the driver, if desired, withoutraising the same by hand.\Vhen the arm A is raised, staples like a, b, or c, or suspension ringstaples, like (I, Fig. 5, may be inserted in the open end of thestapleguiding channel A, and when the arm is depressed and the plungerforced down they will be driven through any papers interposed betweenthe driver and clincher, and the legs bent inward or clinched upon thegrooved face of the anvil 3. B is a stiffening-rib on the base, and B asliding guide to regulate the distance from the margin of the papers atwhich the staples are to be driven.

Referring to Fig. 2, A is the driver-head of the swinging arm A, to thefront face of which is attached, by screws A" A A" A,a front plate, I),(see Fig. 1,) which holds the parts in place and is suitably recessedfor the purpose. F is a staple driver or plunger, supported by thecoiled spring F, and reciprocating vertically in a channel in the head,as shown. It is pro- 'vided at its upper end with a large roundedhind-knob, F; oralcvermaybeusedinstead,or in power-machines a rotatingcare, so that by pressure upon the head of the plunger the same will beforcibly driven down. F is a blade forming a downward extension from thebottom of the plunger F, and it rests above the crown of a staple whenin position for driving, which said staple is driven downward through anarrow staple-guiding channel, A, as the plunger descends. \Vhen aclincher is used, the legs are clinched upon the grooved anvil 13*beneath. E is a transversely-reciprocating head-block or carrier, whichtraverses laterally across the line of vertical motion of the plunger Fand the driv ing-blade F, and a groove, E, is made in the rear side ofthe carrier E, which permits the vertical passage of the blade F", asshown in Fig. 1; or the carrier may not extend entirely across the faceof the machine, but may be a transverscly-reciprocati11g bladeapproaching the line of descent of the plunger, and then recedingtherefrom laterally, so that a staple lying in front of the saidtransverse blade would be carried under the plunger by its motion towardthe same; but I prefer to use the grooved head-block E, as it is morecertain of operation, and a staple in the groove 13* would be carried toand fro as the head-block was reeiprocated, so that a fresh staple couldnot enter the groove E until the preceding one had been driven out bythe plunger F. The groove E conforms to the size and shape of a staplelying flatwise therein, the legs pointing downward. lf staples withslightly flaring legs are shown, as in Fig. 7, the groove will beslightly wider below; if staples with straight legs, as in Fig. 7, thesides will be vertical. When pushed to the left, the motion of thehead-block E will be arrested by the stop E, and in its return the head-bloek will be stopped by the lug or stop IE. Within these limits it isfree to travel to the left, and is brought up sharply to the right by aspring, 0, which maybe of any desired form or construction, though Iprefer to use a simple coiled extension-spring, as shown in Fig. l. Vhenpushed to the left, the groove R will occupy the space marked by adotted staple, L. This staple, Fig. 2, lies behind the headblock, and isthe terminal staple of a series strung or otherwise arranged upon alongitudinal stapleholding bar extending back from the dotted staple ofFig. 2 in the manner shown atJ in Fig. 1. This series of staples lyingflatwise against each other is carried forward under tension by aspring-follower, K, (see Fig. 3,) so that the staples, which areprevented from lateral escape by the flap or tongue J, are pressedforward along the slot J", the terminal staple abutting against thesmooth rear face of the headblock or carrier E. if the groove E is emptyand the headbloek E be pushed to the left to its full extent, it willslide along the front:- end of the series of staples until the groove 17" comes opposite the staple-bar J, when a single staple will beprojected into the groove F1 and the series of staples L will move upone space along the slot .l". W hen pressure is removed from the head ofthe carrier E the spring 0 will suddenly return the carrier to itsplace, and the groove E-', carrying the staple, the latter will beplaced directly under the driving-blade F. A blow upon the top of theplunger F will drive the blade F down through the groove E and thestaple-guiding channel A, carrying the staple before it, and drive thelegs of the staple into any suitable material beneath.

It will be seen that the plunger cannot descend unless they carrier isin place, with its groove ll beneath the same, nor can two or morestaples be carried under the blade F at one time, as the staple willremain in the groove F1 ifit be again reciprocated, and block theentrance to any succeeding staple until the former one be driven out bythe descent of the plunger.

As the staple has sometimes a tendency to drop a little in the groove Ftwhen carried over the stapleguiding channel A", unless somewhatcarefully fitted, so that the legs are likely to be caught and thestaple injured by being carried back accidentallya second time in thecarrier, I usually make the carrier E of hardened steel and magnetizeit, or provide it with a suitable holding attachment, so that a staplelying in the groove E will be attracted and adhere to the bottom of thesame without tendency to slip or drop. I also sometimes, instead of thecarrier, magnetize the drivingblade F, so that the staple will slidealong its ITO under surface in contact therewith; but I prefer theformer, and if the parts are carefully.

fitted the staple will be held mechanically and no magnetization will benecessary.

As often as the carrier is reciprocated and the staple driven out a newone may be taken up and the operation go on continuously until thestaples upon the bar J are exhausted, when the bar is removed and afresh one filled with staples is put in place. I make these bars to holdfrom one hundred to five hundred or more staples, and usually providethem of wood or other cheap material, and furnish them already filledfor use in the machine, and they may be thrown aside when empty orrefilled at pleasure.

-While the bar J is in use, or at any time it may be desired to usestaples of odd sizes, such as are not at the time upon the feed-bar, orto use a suspension-ring staple, such as is shown at d, Fig. 5, in suchcase the carrier E is merely left in place, instead of beingreciprocated, and the arm A being raised, as shown in Fig. 5, thestaples are inserted singly at the open end of the staple-guidingchannel A crown first, and when the bar is brought down the staple willbe driven and clinched, as in ordinary single-feed staple-insertingmachines. To accommodate the laterally-extended loop of asuspension-ring staple, as shown at d, Fig. 5, the rear side of thestapleguiding channel A is recessed at its middle part, with a notchextending through the same, as shown at A", Fig. 2.

Instead of operating the carrier E by indeendently working it laterallyto the left, I metimes use a rightangled lever to move the same to theleft by a vertical motion of the arm, the lower end of which is pivotedto the sliding carrier, and the angle pivoted to the frame of the driverD; and, in power-ma chines, for instance, I sometimes attach this leverto the plunger, so that the upwardmotion of the plunger may operate thecarrier, or I work the carrier and the plunger from one or more cams bythe same belt or gearing. For a simple cheap hand-machine I prefer theform shown in Fig. 2.

The face-plate D is screwed onto the face of A and holds the plunger,the springs, and the carrier in place, forming a case for the same. Theline of parting of the castings is shown in Fig. 4. It will be seen thatthe front of A is substantially a flat surface, the grooves and channelsfor the most part being formed in the cap D. The hollow roll or head Dconlains the spring 0, which may, however, lie outside, if desired. Thehead-block E reciprocates in grooves somewhat wider than the groovedbead D. down from D. nearly to the headblock E, and at E is a screw orpost raised upon the front side of E. A coiled spring, 0, stretched fromone to the other, serves to return the carrier to its place and hold itthere. The vertical groove D crosses the groove D, and, in conjunctionwith an opposite groove on A car- At D is a post extending ries theplunger F. At the lower part of D the staple-guiding channel A is alsopreferably formed in the cap D, through which, as well as through E, theplunger-blade F descends in driving the staple. I modify my machine todrive shoenails, tacks. glaziers points, 850.,

Without departing from the principles of my invention, as will beobvious to any one skilled in the art to which it pertains.

The construction of the staple bar or rod J, to which, however, I makeno claim in this application, except as a part of my genericcombination, is clearly shown in Fig. 6, and in end view in Figs. 7 and7. It consists of a long rod of wood or metal, substantially ofthesectional form shown, and is provided with a tongue or flap, J,extending along the top of the same, attached at one end to leave anopen groove, J, rather wider than the thickness of the wire of which thestaples are made, and which staples I usually make of Bessemer or othersteel or iron wire, and having the op posite end of the tongue or flap Jfree, so that the staples may be pushed out of the slot J by a followermoving behind, the flap J acting as a guide to prevent their beingpushed off at the side, and directing them along the slot and out fromthe open end of the same. I usually prefer to make these staple-bars ofwooden strips of a proper size and length, sawing the slot J into thesame from one end nearly to the; other with a band-saw or other smoothsaw. The unsawed end I prefer to protect against splitting by a smallnail, J. Having strung this bar full of staples, I secure them by tyinga cord or elastic band over the end, as shown in Fig. 6 at J", whichsecurely holds the flap down and keeps the staples in place. Instead ofa cord or band, a small nail may be used; but I do not prefer it, asitroughensthe deli very space. These staple bars,'already filled may beprovided, at no perceptible advance in price, over staplesin boxes, andthey are all ready for use in the machine.

lt will be seen (see Figs. 6 and 8) that the end of the flap J isbeveled or provided with an offset, J'". \Vhile not absolutelyessential, I prefer to use this to keep the slot J open while thestaples are being fed into the machine. Upon D is a beveled projection,D, matched to J, so that when the staple-bar is pushed into the machinethe bevel J of the flap J will impinge against and rise upon the bevel Dof the machine, thus spreading the slot J and holding it open. Where thefollower-spring is of considerable strength, this will usually sufficewithout these bevels or oil'- sets. A filled bar, J, being ready to beinserted into the machine, the front end willbe inserted, the band J 7having been removed or stripped back underneath -the overhanging head Aof the machine and over the socketed support A", Fig. 8. The middle orrear part of the bar J will be supported by the clamp A A, attached tothe arm A. Restingin place in the clamp, it is tightened up by the screwin Fig. 7 or the springclampin Fig. 7. The

front end of J is closely applied to the rear face of the carrier I. ThespringfollowerK. which is attached in the figures to one end of a clockor other spiral spring, M, turning upon a post, M, to which its innercoil is fastened, is drawn back and hooked over the end of thestaple-bar J, the projections K K of the follower K, or a smallremovable pin in lieu thereof, as shown, (see Fig. 3,) entering throughthe grooves J J, made in the unsawed end of J, and traveling along thegroove or slot J, so as to push the staples along. The lower parts ofthe sides of K extend down alongside the red .I and embrace the legs ofthe staples Ii, so as t 0 push them evenly along. At Ii the sides areshown extending in advance of the body of K, to pass into the machineand deliver the final staples of the series. The clamp A" A may beanywhere along the length of the rod J, and I sometimes place it so asto hind at J at the unsawed end of J.

\Vhilc I prefer to feed from my staple-bar directly into the machine, Isometimes strip the staples from my bar, provided with itsretainingtongue or flap J' onto a metal bar permanently fixed in themachine. The de tachable bar, however, enables the mechanism to beexamined from behind, should a staple catch, by merely detaching the barJ, instead of taking off the plate I), as would otherwise be requisite.Instead of the clock-spring M )1", I sometimes use a simple coiledspring or an elastic band; but I prefer to use the form shown as beingmore sensitive and COl'lVOllICllh.

\Vhen the clincher I3 is not required, as when a simple driver is used,I dispense with the base 13 and its parts and furnish the selffeedingdriver, as above described, without aclinchcr, and with or without ahandle, A. For making up boxes, upholstering furniture, wiring blinds,and for various other purposes my invention isthns extremely desirable.

Instead of having the carrier reciprocate in a right line transverselyto the axis of the plunger, I sometimes construct it to move at variousangles thereto, or upon the arc of a circle, and I otherwise variouslymodify my machine without departing from the principles of my inventionas hereiuabove set forth.

Having now described my invention, what I claim, and desire to secure byLetters Iatcut, is
